Fish stocks on a stretch of the River Trent in Staffordshire that was polluted with cyanide appear to have been wiped out, experts have said.

Investigations are continuing into the source of last week's chemical leak near Stoke-on-Trent.

............

Severn Trent Water, which was not linked in any way to the chemical, said the cyanide had been released into the sewers upstream from the company's Strongford sewage treatment works in Stoke.

That caused problems at the works and resulted in partially-treated sewage also being released into the river.

Considering that Industry nowadays is pretty good at keeping on top of this sort of thing, is it possible that the cyanide came from one of Stoke's many followers of the Religion of Peace who had decided to give up on the Jihad?

There were arrests in Stoke before at the time of the Glasgow Airport Attack.
